Arrangement for gasifying finely divided particularly solid fuel under high pressure

Abstract

An arrangement for and a method of gasifying finely divided, particularly solid fuel under increased pressure with a multi-pipe wall having a plurality of pipes arranged to be supplied with a cooling medium, the multi-pipe wall limiting a gas-collecting chamber and also limiting a plurality of recesses which form combustion chambers, wherein each of the recesses having a plurality of parameters including a depth, a width and an angle of inclination of a peripheral wall and being such that at least one of the parameters is changeable

What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims: 
     
       1. An arrangement for gasifying finely divided, particularly solid fuel under increased pressure, comprising a multi-pipe wall having a plurality of pipes arranged to be supplied with a cooling medium, said multi-pipe wall limiting a gas-collecting chamber and also limiting a plurality of recesses which form combustion chambers, each of said recesses having a plurality of parameters including a depth, a width and an angle of inclination of a peripheral wall and being such that at least one of said parameters is changeable in accordance with operational conditions, said multi-pipe wall including a plurality of first multi-pipe wall portions which limit said recesses and a second multi-pipe wall portion which limits said gas-collecting chamber and are disconnectable and releasable from one another so that at least one of said first multi-pipe wall portions which limits one of said recesses can be removed and replaced by another different first multi-pipe wall portion which limits another different recess; and means for disconnectably and releasably attaching said at least one first multi-pipe wall portion to said second multi-pipe wall portion. 
     
     
       2. An arrangement as defined in claim 1; and further comprising means for withdrawing a gas from said gas-collecting chamber above the latter. 
     
     
       3. An arrangement as defined in claim 1; and further comprising means for withdrawing a slag from said gas-collecting chamber under the latter. 
     
     
       4. An arrangement as defined in claim 1; and further comprising means for supplying a cooling medium into said pipes of said multi-pipe wall. 
     
     
       5. An arrangement as defined in claim 1, wherein said gas-collecting chamber has a chamber wall, the depth of each said recesses being changeable by arranging of said multi-pipe wall at different distances from said chamber wall. 
     
     
       6. An arrangement as defined in claim 1, wherein said collecting chamber has a chamber wall, said recesses having recess walls of different diameters, the width of said recesses being changeable by inserting into said chamber wall of recess walls of different diameters. 
     
     
       7. An arrangement as defined in claim 1, wherein said collecting chamber has a chamber wall, said recesses having recess walls with different angles of inclination, the angle of inclination of said recesses being changeable by inserting into said chamber wall of recess walls of different angles of inclination. 
     
     
       8. An arrangement as defined in claim 1, wherein said multi-pipe wall portions are provided with independent cooling supply and withdrawal means. 
     
     
       9. An arrangement as defined in claim 1, wherein said second multi-pipe wall portion of said gas-collecting chamber has a throughgoing point formed so that said at least one first multi-pipe wall portion of said one recess can be placed therein. 
     
     
       10. An arrangement as defined in claim 9, wherein said throughgoing point is formed by bending of pipes of said second multi-pipe wall portion of said gas-collecting chamber so as to form a pipe collar. 
     
     
       11. An arrangement as defined in claim 9, wherein said throughgoing point is formed by said pipes of said second multi-pipe wall portion of said gas-collecting chamber by bending said pipes; and further comprising a collecting pipe which is arranged prior to said throughgoing point and in which said pipes of said second multi-pipe wall portion are open in the region of said throughgoing point. 
     
     
       12. An arrangement as defined in claim 9, wherein said throughgoing point is formed by said pipes of said second multi-pipe wall portion of said gas-collecting chamber which are bent; and further comprising a collecting pipe in which said pipes of said second multi-pipe wall portion are open and which forms a periphery of said throughgoing point. 
     
     
       13. An arrangement as defined in claim 9, wherein said throughgoing point is formed by said pipes of said second multi-pipe wall portion of said gas-collecting chamber; and further comprising a plurality of angular-shaped members in which said pipes of said second multi-pipe wall portion are open in the region of said throughgoing point. 
     
     
       14. An arrangement as defined in claim 9, wherein said throughgoing point has a periphery; and further comprising a sealing system provided over said periphery of said throughgoing point for sealing said recesses from said gas-collecting chamber. 
     
     
       15. An arrangement as defined in claim 9, wherein said throughgoing point is closable; and further comprising means for closing said throughgoing point and including a cover plate provided with cooling pipes. 
     
     
       16. An arrangement as defined in claim 15; and further comprising a burner arranged on said cover plate; and means for protecting of said burner from a slag and including a slag-deflecting protective shield. 
     
     
       17. An arrangement as defined in claim 16, wherein said slag-deflecting shield is formed by pipe pieces projecting from said cover plate. 
     
     
       18. An arrangement as defined in claim 15, wherein said pipe pieces are provided with a layer of a fire-resistant material. 
     
     
       19. An arrangement for gasifying finely divided, particularly solid fuel under increased pressure, comprising a multi-pipe wall having a plurality of pipes arranged to be supplied with a cooling medium, said multi-pipe wall limiting a gas-collecting chamber and also limiting a plurality of recesses which form combustion chambers, each of said recesses having a plurality of parameters including a depth, a width and an angle of inclination of a peripheral wall and being such that at least one of said parameters is changeable in accordance with operational conditions, said multi-pipe wall including a plurality of first multi-pipe wall portions which limit said recesses and a second multi-pipe wall portion which limits said gas-collecting chamber and are disconnectable and releasable from one another so that at least one said first multi-pipe wall portions which limits one of said recesses can be removed and replaced by another different first multi-pipe wall portion which limits another different recess; means for disconnectably and releasably attaching said at least one first multi-pipe wall portion to said second multi-pipe wall portion, said second multi-pipe wall portion of said gas-collecting chamber having a throughgoing point formed so that said one first multi-pipe wall portion of said recesses can be placed therein, said throughgoing point being closeable; and means for closing said throughgoing point and including a cover plate provided with cooling pipes.
